Example of Information Collected from this web site for Statistical Purposes
Below is an example of the information collected based on a standard request for a World Wide Web document.
xxx.yyy.com - - [28/Jan/1997:00:00:01 -0500] "GET /news/nr012797.html HTTP/1.0" 200 16704 Mozilla 3.0/www.altavista.digital.com
xxx.yyy.com (or 22.214.171.124) -- this is the host name (or IP address) associated with the requester (you as the visitor). In this case, (.com) the requester is coming from a commercial address. Depending on the requester's method of network connection, the host name (or IP address) may or may not identify a specific computer. Connections via many Internet Service Providers assign different IP addresses for each session, so the host name identifies only the ISP. The host name (or IP address) will identify a specific computer if that computer has a fixed IP address.
[28/Jan/1997:00:00:01 -0500] -- this is the date and time of the request
"GET /news/nr012797.html HTTP/1.0" -- this is the location of the requested file on the web server 200 -- this is the status code - 200 is OK - the request was filled
